Luke 10-- Maybe here are the other apostles

In light of the post below, it dawned on me that we do have Jesus expressly sending out others who are not the Twelve. (Remember that "apostle" means "sent one.") In Luke Jesus sends out the 72, just as he sent out the twelve in Luke 9.

So perhaps these are the other apostles whom Paul refers to. Or, at least, perhaps these 72 are included among the other apostles.
